previously i purchased the wadar from here which turned out reallly good and comfortable for me. After that, like few days back i received the rio directcore bonefish fly line that i ordered. its really good and have very amazing long head and rear taper for smoothing the loop. It helps in making the casts efficient and much easier,
There are strength range which follows like
WF6 – WF7 = 30lb
WF8 – WF9 = 40lb
( aslo mentioned on its website)
Apart from this, here are few things i noticed :
the high floating line doesn't sink during the wading which is really good
also the price is affordable and quite reasonable to me. So the deal is really cool.
